Screening of effective fraction on experimental gastric ulcer from Pongamia pinnata roots / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of extract from Pongamia pinnata roots on experimental gastric ulcer and screen the effective fraction.</p><p><b>METHOD</b>The models of gastric mucosa damage were induced by absolute alcohol in rats and reserpine in mice to observed the effect of ethyl alcohol extract from P. pinnata roots (PRE) and different parts on experimental gastric ulcer.</p><p><b>RESULT</b>PRE, acetic ether extract and n-butanol extract could significantly inhibit the gastric mucosa damage induced by absolute alcohol in rats and reserpine in mice. In absolute alcohol models the gastric ulcer rates of inhibition were 86.4%, 85.4%, 11.5%, respectively. In reserpine models the gastric ulcer rates of inhibition were 37.8%, 33.8%, 19.7%, respectively.</p><p><b>CONCLUSION</b>PRE, acetic ether extract and n-butanol extract could significantly inhibit the gastric mucosa damage induced by absolute alcohol in rats and reserpine in mice. Acetic ether extract from P. pinnata roots has the best effect on experimental gastric ulcer.</p>
